DETAILED DESCRIPTION OF SOME EMBODIMENTS

The following embodiments are exemplary. Although the specification may refer to “an”, “one”, or “some” embodiment(s) in several locations, this does not necessarily mean that each such reference is to the same embodiment(s), or that the feature only applies to a single embodiment. Single features of different embodiments may also be combined to provide other embodiments. Furthermore, words “comprising” and “including” should be understood as not limiting the described embodiments to consist of only those features that have been mentioned and such embodiments may contain also features/structures that have not been specifically mentioned.

The present invention is applicable to any piece of a system and the system that comprises one or more service centers or service desk equipment configurable to transmit instructions and recommendations to a remote user apparatus. In the following, maintenance is used as an example of a remote service without restricting the examples to the maintenance.

An extremely general architecture of an exemplary system 100 is illustrated in FIG. 1. FIG. 1 is a simplified system architecture only showing some elements, functional entities, which are logical units whose implementation may differ from what is shown, and some equipment. It is apparent to a person skilled in the art that the system may comprise any number of shown elements, other equipment, other functions and structures that are not illustrated.

In the embodiment illustrated in FIG. 1, the system 100 comprises one or more industrial sites 101 (only one illustrated in FIG. 1) connected over one or more networks 102 to one or more service centers 103 (only one illustrated in FIG. 1) and to one or more service desks 140 (only one illustrated in FIG. 1) either directly over one or more networks 102 or via the service center.

In the illustrated example the industrial site 101 comprises a user apparatus 110 of a remote user as visiting equipment, and a terminal device 120 and a drive 130 as permanent equipments. The permanent equipment means herein equipment that is intended to locate in the industrial site a long time, whereas the visiting equipment means equipment that is intended to visit the industrial site temporarily. However, it should be appreciated that the user apparatus 110 may be permanent equipment as well. Further, it should be appreciated that the terminal device and the drive depicts herein any device, machine, equipment, system and a process that whose operations and/or service and/or maintenance may be taken care remotely. Other examples of such equipment include frequency converters, alternating current/direct current (AC/DC) modules, direct current/alternating current (DC/AC) modules, programmable logic controllers, switches, motion controllers or motion drives, servo motors, soft starters, robots, cars, and heavy equipment, etc. It should be appreciated that in the above only some examples are listed.

The user apparatus 110 refers to a computing device (equipment), that may be a non-portable device or a portable device (mobile device), and it may also be referred to as a user terminal or user device. Portable computing devices (apparatuses) include wireless mobile communication devices operating with or without a subscriber identification module (SIM) in hardware or in software, including, but not limited to, the following types of devices: mobile phone, smart-phone, personal digital assistant (PDA), laptop and/or touch screen computer, tablet (tablet computer), multimedia device, wearable computer and other types of wearable devices, such as clothing and accessories incorporating computer and advanced electronic technologies. The user apparatus 110 is configured to support remote maintenance. For that purpose the user apparatus 110 comprises a remote support application provided by a remote tool unit (r-t-u) 111 (may also be called a remote support tool unit), and its sub-unit remote live support unit (r-l-s-u) 111-1 whose functionality will be described in more detail below with FIGS. 2 and 3.

In the illustrated example the user apparatus has at least two communications interfaces, depicted by 2 antennas, one to connect to the service center 103 wirelessly over one or more networks 102 and one to connect to the terminal device 120 over a local connection. The wireless connection to the service center may be provided by any mobile system, such as Global System for Mobile communications (GSM), General Packet Radio Service (GPRS), Long-Term Evolution (LTE), 4G, 5G and beyond, or a combination of a mobile system and a fixed system, like Wi-Fi or Li-Fi providing access to internet and via internet to the service center. The local connection may be provided naturally over a mobile system but it may be provided by a direct connection, for example using Bluetooth, or by a local network, like Wi-Fi or Li-Fi. It should be appreciated that the user apparatus 110 is depicted to include 2 antennas only for the sake of clarity. The number of reception and/or transmission antennas, or other communication interfaces, may naturally vary according to a current implementation, and the user apparatus type.

The terminal device 120 refers herein to equipment via which parameters of the drive 130 may be adjusted or acquired, and the functions of the drive 130 otherwise controlled by a person located on the site and/or remotely from the service center. In other words, the terminal device is a module providing at least a wireless interface to which the user apparatus may connect to. The terminal device 120 may be a separate device (as in the illustrated example), or a device detachable connectable to the drive, or equipment integrated to the drive. At the simplest the terminal device may be the mere wireless interface. Other examples of the terminal device include a control panel, smartphone, mobile phone, tablet or laptop computer. At least in the solutions in which the terminal device 120 is not integrated with the drive 130, the terminal device 120 may be located on-site at a close proximity of the drive 130 to which a connection may be provided via a communication interface by Bluetooth, Near-field communication (NFC), WiFi, Li-Fi, and/or inductive connection (such as an inductive connection according to an inductive power standard (Qi) by the Wireless Power Consortium), for example.

In the illustrated example of FIG. 1 the drive 130 is equipment performing the functionality of a drive according to its settings and has a communication interface via which its parameters may be adjusted or acquired by means of the terminal device 120.

The one or more networks 102 (communications networks) may comprise one or more wireless networks, wherein a wireless network may be based on any mobile system, such as GSM, GPRS, LTE, 4G, 5G and beyond, or a wireless local area network, such as Wi-Fi, Li-Fi. Further, the one or more networks 102 may comprise one or more fixed networks and internet.

In the illustrated example the service center 103 comprises a service desk 140 and a server 150. The service desk 140 may be any combination of any user interface, like touch screen or combination of a display and a keypad, and any computing apparatus. Examples of such apparatuses include a work station, a laptop computer, a personal computer, a wearable computer and a display connected to the server 150. The service desk 140 is configured to support the live remote maintenance. For that purpose the service desk 140 comprises a live support unit (l-s-u) 141 whose functionality will be described in more detail below, and a connection to the server 150. The service desk 140 may be configured to have a connection to the site via the server and/or over one or more networks 102, and the network(s) used may be different than those used by the server 150.

The server 150, like a cloud server or a grid server, refers herein to a combination of a data storage and a data management system. The data storage may be any kind of conventional or future data repository, including distributed and centralized storing of data, a cloud-based storage in a cloud environment, managed by any suitable management system. The implementation of the data storage, the manner how data is stored, retrieved and updated are irrelevant to the invention, and therefore not described in detail here. The server 150 is configured to support the live remote maintenance. For that purpose the server 150 comprises a live feed unit (l-f-u) 151 whose functionality will be described in more detail below, a connection to service desks 150 and a connection over the one or more networks 102 to the site.

FIG. 2 illustrates information exchange in an exemplary situation in which a remote live session is established between a user of a user apparatus UA in a site, and an operator of a service desk SD1, the remote live session being established via a server supporting remote maintenance for example. Further, in the illustrated example it is assumed that the terminal device is integrated into the drive, and that they function as one unit, the drive. Further, in the example it is assumed that alerting is triggered by sending a corresponding message and the alerting is continued as long as a message stopping alerting is received. However, it is a straightforward solution to implement the functionality disclosed below to a solution in which alerting is continued as long as alerting messages are received (and naturally sent) at a certain intervals. It should be appreciated that any known or future communication protocol and process to establish a session/connection may be used. Therefore they are not described in detail herein.

Referring to FIG. 2, when the user stars the remote tool application, remote app, (point 2-1), a local connection to the drive is establish (messages 2-2, denoted by a dash line) and a connection to the server (messages 2-3). The server is a back-end server to the remote tool application, and hence the server's address is known by the remote tool application. However, unlike in prior art solution, the user apparatus outputs in the remote tool application a possibility to start a live support, and once a user input selecting to start a live support session is detected in point 2-4, the remote live support unit is started and the remote live support unit causes transmission of a request for live support session in message 2-5 to the server.

The server detects in point 2-6 that instead of retrieving information or storing information, the user apparatus sent a request for a live support session. Therefore the server starts the live feed unit for the session (unless it is already running), and the live feed unit triggers session establishment by causing sending session invitations 2-7, or corresponding session establishment requests, to service desks SD1, SD2. The service desks to whom invitations 2-7 are sent may be selected freely. For example, the server, or more precisely the live feed unit, may send invitations to each service desk coupled to the server, or whose address information the server knows, or to a subset of the service desks. For example, certain sites and/or drives may be associated with certain service desks, and/or certain users may be associated with certain service desks, such association information being maintained in the server, for example, retrievable by the live feed unit.

When a service desk SD1, SD2 receives the invitation for a live support session, the live support unit is started (unless it is already running), and an alert is outputted in point 2-8 via a user interface so that an operator of the service desk may notice (see and/or hear and/or feel) the alert.

In the illustrated example the service desk SD1 receives in point 2-9 as an operator (user) input an acceptance to the invitation. In other words, the operator answered to the alert. Therefore the live support unit causes sending the acceptance in message 2-10.

Upon receiving message 2-10, the live feed unit in the server detects that SD1 accepts the session invitation, and therefore causes in point 2-11 the user apparatus and the service desk SD1 to connect to each other. Typically the connection passes via the server. However, it is possible that within the session a voice call is established directly between the user apparatus and the service desk, while the session is maintained between the user apparatus and the server, or the session is extended to be between the user apparatus and the service desk, via the service desk. For example, in a multimedia call, voice path may be over a direct connection between the user apparatus and the server, while image information, and other data information passes via the server. Further, the live feed unit informs (message 2-12) the other service desks to stop alerting. Upon receiving message 2-12 the live support unit in the service desk detects that alerting should be stopped, stops in point 2-13 the alerting, and shuts itself (unless needed for other user apparatuses).

Meanwhile the live session has been established between the service desk SD1 and the user apparatus, messages 2-14 illustrating session establishment and information exchange between them (or the live support tool and the remote live support tool). Since the user apparatus has a connection to the drive, a connection is, in the illustrated example, established also between the service desk SD1 (or the live support tool) and the drive so that the service desk SD1 has access to the drive and may obtain information directly from the drive and/or store information and/or set parameters, or service counters, etc. directly to the drive, messages 2-15 illustrating the connection establishment and information exchange between them. Preferably, if a connection is established between the service desk and the drive, via the user apparatus, the user of the user apparatus is prompted to approve access from the service desk to the drive. This provides safety against fraudulent use. However, the user apparatus, or the remote life support unit, may be configured to allow the service desk access to the drive without user approval. Further, it should be appreciated that a connection between the service desk and the drive is not necessary, and hence may not exits. The same applies to the connection between the user apparatus and the drive: a live support session may be between the user apparatus and the service desk also when there is no local connection from the user apparatus to the drive.

To have a direct connection from the user apparatus to the drive, and a direct connection from the service desk to the drive, enables versatile possibilities. For example, the user in the drive site may, while chatting with the operator, to execute a script with the drive, and after that also comment the result of that. The operator may, thanks to the direct connection to the drive, request or retrieve information from the drive directly, without first describing what he/she wants to have to the user of the user apparatus. Further, the operator may cause command(s) and/or actions to be performed, and/or scripts run on the drive without the user of the user apparatus being involved or noticing anything. However, thanks to the live support session, the operator may ask the user the end result of the “direct drive manipulation”. Hence this improves the customer support quality and will decrease the malfunction time, or at least average time the drive cannot be used, hence increasing productivity.

After a while either the operator or the user provides as a user input “end the live remote session”. In response to receiving, or detecting in point 2-16 information indicating to end the session, the live feed unit releases in point 2-16 the session and the connection and resources reserved for them. Further, the live feed unit may shut down, unless needed for other corresponding sessions.

FIG. 3 illustrates an exemplary functionality of the remote live support unit and/or the live support unit. The functionality of the two units is similar, and hence there is no need to describe them separately. Basically the only difference between the units are that the remote live support unit is run in an apparatus in a remote site (industrial site in FIG. 1), whereas the live support unit is run in an apparatus in a support site (service center in FIG. 1). In the example illustrated in FIG. 3 it is further assumed that the live support session is ended either in response to the user of the corresponding apparatus (user apparatus in the site, or the service desk) providing such an input, or corresponding input is received from the other apparatus with which the live support session has been established. For the sake of clarity, in the illustrated example it is assumed that if one of the parties call, the other one answers to the call. It should be appreciated that if the other one rejects the call, or the alerting stops before the other party has answered the call, no connection is established for the call.

Referring to FIG. 3, the live support session is established in step 301, as described above with FIG. 2. After step 301, there is a session to the other apparatus and a connection to the drive. Then it is monitored, whether a user input is received (step 302: yes) via a user interface (UI) of the apparatus or as received information from the other apparatus (step 302: no).

If the user input is received via the user interface of the apparatus (step 302: yes), in the illustrated example it is assumed that the user input may relate to live chat, sharing images (images are used as an example of any data sharing, such as different documents, audio clips video clips, i.e. files of any type), to drive data, to a call (covering both a video call and a voice call) or to ending of a session.

If the user input relates to live chat (step 303: yes), the inputted information, comprising text and/or characters and/or icons, for example, is outputted in step 304 on the user interface of the apparatus and sending the information is caused in step 304 to the other apparatus, so that the other party chatting sees the same information. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the user input relates to images (step 303: no, step 305: yes), the user may be provided to select, whether to capture an image or use an existing image, and once the image is selected in step 306, either by capturing and/or selecting amongst existing images, or if an existing image is used, the image is outputted in step 306 on the user interface of the apparatus and sending the image is caused in step 306 to the other apparatus, so that the other party chatting sees the same image. Then the process returns to monitor, whether a user input is received (step 302: yes) or information from the other apparatus (step 302: no).

If the user input relates to drive data (step 305: no, step 307: yes), then the drive data is obtained and processed in step 308. For example, the remote application may cause reading (obtaining) fault codes and/or warnings and storing to the memory, setting parameters and/or service counters. The drive data may be shown to the user. Further, the remote application may cause showing the drive data to the user and/or forwarding the drive data to the service desk. In the service desk side, sending queries to obtain the drive data and/or parameter values and/or different instructions, like setting service counters, may be caused, for example. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the user input relates to a call (step 307: no, step 309: yes), it either indicates that the user wants to establish a call or end an ongoing call. Herein establishment covers answering to an alerting call, or triggering a call establishment. If the user wants to establish a call (step 310: yes) by responding to an alerting call, establishing the call to be carried over the existing session is caused in step 311, and then the parties (the user of the user apparatus and the operator of the service desk) may hear, and in case of a video call also see, each other. If the user wants to establish a call (step 310: yes) by triggering a call establishment, alerting the other party (or parties) is caused in step 311, ending eventually to establishing the call to be carried over the existing session, and then the parties (the user of the user apparatus and the operator of the service desk) may hear, and in case of a video call also see, each other. It should be appreciated that the call may use another communication path than the live support session even though the call is established to be carried over the existing session. Even, when there is an ongoing call, the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no). If the user does not want to establish a call (step 310: no), the user want to end an existing call. Therefore releasing the extra resources reserved for the call is caused in step 312, the releasing including sending corresponding information to the other apparatus. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the user input indicates that the user wants to end the live support session (step 309: no), the live support session is ended in step 313. However, if the process is run in the user apparatus, the remote support application is still running, and its use according to prior art possibilities may continue.

If user input is received information from the other apparatus (step 302: no) in the illustrated example it is assumed that the received information may relate to live chat, sharing images (images are used as an example of any data sharing, such as different documents, files and/or videos), to drive data, to a call (covering both a video call and a voice call) or to ending of the session. Further, it should be appreciated that the received information from the other apparatus may actually be also something else than a user input of the user of the other apparatus, herein the received information is interpreted to correspond to actual user input.

If the information from the other apparatus relates to live chat (step 314: yes), the information is outputted in point 315 on the user interface so that the user sees what the other party is chatting. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the information from the other apparatus relates to images (step 314: no, step 316: yes), the image is outputted in point 315 on the user interface so that the user sees the image. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the information from the other apparatus relates to drive data (step 316: no, step 317: yes), the drive data is processed in step 318 accordingly. For example, the received drive data may be shown to the user. Further, the remote application may receive instructions to set parameters and/or service counters, and corresponding setting is caused, for example, or the remote application may receive an inquiry and reading (obtaining) fault codes and/or warnings and/or parameters, or corresponding settings, and forwarding them to the service desk is caused. In the service desk side, responses to queries to obtain the drive data and/or parameter values and/or different instructions, like setting service counters, may be received, for example, and processed correspondingly. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the information from the other apparatus relates to a call (step 317: no, step 319: yes), it either indicates that the other user wants to establish a call, and therefore either an alert or an acceptance is received, or the other user wants to end an ongoing call. If the received information indicates that the other user wants to establish a call (step 320: yes) and an alert is received, alerting is caused in step 321. If the received information indicates that the other user wants to establish a call and an acceptance is received (step 320: yes), a received user input answering to the call (alert) is detected in step 321 and therefore establishing the call to be carried over the existing session is caused in step 321. After that he parties (the user of the user apparatus and the operator of the service desk) may hear, and in case of a video call also see, each other. Even, when there is an ongoing call, the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no). If the other user does not want to establish a call (step 320: no), the other user wants to end an existing call, and corresponding information is received. Therefore releasing the extra resources reserved for the call is caused in step 322. Then the process returns to monitor, whether a user input is received (step 302: yes) via the user interface of the apparatus or as received information from the other apparatus (step 302: no).

If the received information indicates that the other party wants to end the live support session (step 319: no), the live support session is ended in step 313, as described above.

As is evident from the above, the user's view may comprise images, sent chats, and received chats, for example, in any order. The live support unit, and the remote live support unit, aggregates the different media types. This facilitates finding a solution and receiving a general view, since everything is in the aggregated format, one does not need to jump between an email and a chat application. This in turns decreases the time, at least an average time, the drive cannot be in use. The shorter the time the drive is not in use, the better the productivity is.

It should be appreciated that the above illustrated different information types (media types) are only exemplary and it is a straightforward solution to implement the above description to other types of information. Any type of media format, including different multimedia formats, may be exchanged.

Since there is no need to close the remote support application to use another application, like capturing a picture and sending it via email, or to dial a number for phone service, time is saved and use of false addresses or false numbers is avoided (thanks to the application being up and running and knowing the addresses). This all decreases the time the drive cannot be in use, and as said above, this increases productivity.

The steps, points, related functions, and information exchanges described above by means of FIGS. 2 and 3 are in no absolute chronological order, and some of them may be performed simultaneously or in an order differing from the given one. Other functions can also be executed between them or within them, and other information may be sent. Some of the steps or points or part of the steps or points or one or more pieces of information can also be left out or replaced by a corresponding step, point or part of the step, point or one or more pieces of information. For example, it should be appreciated that the user input received via a user interface and/or as received information may relate only one, two or three of the examples mentioned above with FIG. 3, and/or further information exchange not expressly mentioned may be involved, using the above described principles.

The techniques and methods described herein may be implemented by various means so that a user apparatus/user device, a service desk/service desk device and/or a server/database server configured to support live remote support, that may be called also remote live user support, based on at least partly on what is disclosed above with any of FIGS. 2 and 3, including implementing one or more functions/operations of a corresponding user apparatus and/or service desk device and/or a server described above with an embodiment/example, for example by means of FIG. 2 or FIG. 3, comprises not only prior art means, but also means for implementing the one or more functions/operations of a corresponding functionality described with an embodiment, for example by means of FIG. 2 or FIG. 3, and it or they may comprise separate means for each separate function/operation, or means may be configured to perform two or more functions/operations.
